Technical details

A memory leak vulnerability (CWE-401) exists in the YUV decoder of ImageMagick. The issue is triggered when the decoder fails to open a blob, resulting in allocated memory not being properly released. While the attack complexity is high, a remote attacker can exploit this over a network without authentication or user interaction. Repeated exploitation can lead to resource exhaustion and a denial of service (DoS) condition. The vulnerability is addressed in versions 7.1.2-26 and 6.9.13-51.
